Scythe FUMA SCFM-1000 Twin Tower CPU Air Cooler

Scythe has a history of building CPU air coolers that not only perform well, but are also are a value in terms of your hard earned money. The FUMA cooler is built with the PC hardware enthusiast in mind and sports multiple fan configurations and comes supplied with two fans so you do not have any added cost.

Scythe FUMA

The FUMA has a lot going for it but I would also say there are a lot of expectations placed upon it. Starting with the easy stuff, the FUMA uses a dual tower design that lends itself to strong cooling potential. Scythe also designed the FUMA with a height of 149mm making it possible to install it in smaller cases than we usually see with coolers like these. The only real negative I would suggest at this early stage is that Scythe has such a strong reputation that the FUMA has a lot to live up to. So far though, things are looking well even with the bar being set high.

Package & Specs

The packaging for the FUMA is solid and complete. Plenty of formed cardboard to keep everything safe.

  • (Editor's Note: While AM4 (RYZEN) socket compatibility is not listed in the specifications, these "clip-on" type coolers will work just fine with upcoming CPUs from AMD. Worth noting however, if your AMD cooling setup is mounted through the holes on the motherboard, you will need a new mount for Ryzen processors.)

    Scythe includes two fans and three sets of fans clips. Scythe also include a Y-cable but this can only support up to two fans, so if you opt for a third you’ll need to account for a power lead, which likely should not be an issue on any modern motherboard.

    Here are some photos of the Scythe FUMA from different angles. The whole kit looks very well made and Scythe used some heavy duty heat pipes with the FUMA.

    On the topic of baseplate material, Scythe has this to say:

    Since there have been some questions regarding the material of the CPU-cooler baseplates, here is some short information. There have been rumors around, that Scythe is using aluminium due to cheaper prices - this is just plain wrong.

    Due to its high susceptibility to oxidation, copper tends to change the surface colour during the long transport from the factory to our distributors. There is no satisfactory way to avoid this optical change. Because of this, all Scythe CPU coolers produced from the beginning of 2008 have a baseplate still consisting of copper, but they are now nickel-plated.

    Installation

    Installing the Scythe FUMA is easy to install given how large it is. It takes a bit of time but is on the easier side as far as these things go. The clearances under the FUMA are ample on all sides.

    An issue can arise when you get to the RAM slots depending on your choice of RAM. Some CPU coolers use an offset design with the heat pipes to push the fins away from the DIMM slots allowing for the use of taller RAM. The FUMA is centered on the CPU socket and the fins on the heatsink extend to the front edge of the first DIMM slot. If you install the fans "low" on the fins, those can get in the way, so you just need to make sure you install the fan's bottom edge close the the heatsink fins bottom edge. If you do this, you should have enough clearance to use all the RAM slots if you have "short" RAM. If you have RAM with taller heatsinks, as we show in the picture, you are likely going to have issues.

    The distance from the bottom of the base to the to the bottom of the fins is 35mm as you can see on the diagram above. When mounted this distance is about 36mm. As you can see in the picture above, standard RAM will fit in this space, but RAM with taller configurations is going to be an issue. Something to surely be aware of.

    Contact with the CPU is the best we would want. Nice even pressure across the base allows for the most efficient transfer of heat between the processor and heat sink base.
